Adaptec scsi 39160 big problem

Hi guys, I bought on ebay this scsi controller but I have a big problem with its settings (I think).
I connected as Id0 a Plextor 40tsi, and as id1 a Plextor 8/20 , but the cdrom transfers data at 10x (it seems a Clv device), and the Cpu usage is very high. (Nero cdspeed gives at 8x an usage of 61% :sad: ).

Bios paremeters are setting to default, sync data transfer is activated… I have also tried a 2940uw, but with this one, for some reasons I can’t boot from cdrom; with this one boot is fine but there are other problems.

I have a p4 3,2 ghz, with mobo Asus p5gd1

Thanks in advance.


Problem solved, installing a driver (sort of service pack) for my scsi controller.
